The spontaneous contraction of the vessel wall during perfusion with MWCNTs (1.0 mg/mL) is in synchrony with the flow of black MWCNT nanoparticles. The MWCNTs in the vessel move faster in the front and back of the valve with vessel contraction, and particles flow beyond the valve during dilation. In both cases, the valve was observed to move across the center of the lymph vessel. Credit Copyright © 2021 Elsevier B.V.
